(A–D) Strength of four identified risk factors for the total cancer outcome 1988–1996. Mantel-Haenszel weighted incidence rate ratios (MH-IRR) as adjusted by age with 95% confidence intervals (95% CI). Homogeneity regions (H region) go from sparse (H6) to dense (H3) populated regions. Lung cancer incidence 1988–1996 was taken as a proxy determinant for an aggregate of risk factors, including smoking, and similarly, the total cancer incidence 1986–1987 was taken as a determinant for total cancer incidence 1988–1996
